RECORDING AND SALES-CHECK MECHANISM FOR FLUID-DISPENSING PUMPS.

Application filed August 16, 1926'. Serial No. 129,614.

The invention relates to means whereby the custou'ier and salesman each. receives a check showing; the amount of fluid dispensed at each sales transaction, the salemans check Y being preferably retained and wound into a roll for convenient and ready reference.

()ne of the purposes of the invention is to eliminate, as much as possible, the leakage, or error attributable to dishonesty or neglect in making charges, and to insure full measure tothe customer in the amount noted on the check.

A further purpose of theinvention is the provision of a mechanism of the character aforesaid whichmay be readily applied to a fluid dispensing pump, such as generally en1- ployed. at service stations, for supplying motor fuel and oil in measured quantity.

The invention furtltier aims to provide a mechanism which is simple, efficient and readily accessible, the working parts being mounted upon a plate which is readily insertable in a casing, and easily removable therefrom as occasion may require.

\Vhile the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention. and the. merits thereof, reference is to be had to ,thefollowing' description and the drawings hereto attached, in which,'

Figure 8 is a" sectional view of the spool upon which the retained portion of thestrip is wound and the spindle therefor, on the nated in the several views of the drawings by like reference characters.

The operating parts of the mechanism are enclosed within a casing designated by the numeral 10 which is open at one side to which is fitteda door 11 which, when closed, is made secure by a suitable lock mechanism to prevent surreptitious entry to the casing and a possible tampering with the mechanism. The front of the casino; is provided with a delivery slot- 12 for the discharge of a portion of the strip corresponding to the sales check for the customer. Blocks 13 are located at the four corners of the casing adjacent the side opposite that closed by means of the roor 11 and these blocks may form a part of the casing; and provide convenient means for supporting a plate 1.4L which is bolted, or otherwise attached thereto, said plate being: readily removable from the easing and constituting a frame for receivii'rg and supporting" the operating parts of the mechanism. Similar brackets and 16 are attached to opposite sides of the plate 14 and project in opposite directions therefrom adjacent the top of the casing 10. The upper edge of the plate 14 is notched to receive the horizontal portions of the brackets 15 and 16, as shown most clearly in Figure 9. The bracket 16 is located near the front of the casing, whereas the bracket 15 is located near the back of the casing. The

. end portions of the brackets remote from the plate M extend downwardly, as shown most clearly in Flgurc 2, and provide convenient means for supporting parts of the mechill fill

til)

anisin which are journaled therein. A shaft 17 journaled in the bracket extends through a side or the casing 10 and is adapted to be coupled to an operating part of the fluid dispensing pump. A disk or plate 18 is made fast to the inner end of the shaft 17 so as to rotate therewith. A plurality ot' pawls 19 are mounted upon the plate 1.8 and are adapted to enact with a spur wheel 20 loose upon the shatt 17. whereby to etliect rotatioi'l ot the shalt and spi ir wheel in one direction. A bevel gear 21 rotatable with the spur gear ill) and preferably forming a part thereof, is in mesh with a bevel pinion t'ast to the adjacent end of. a worm shaft which is mounted in bearings :24 secured to the plate 14, endwise moven'ient of the shaft being prevei'ited by having the ends of the worm 23 engaging the brackets 24:, as shown most clearly in Figure 3. The worm is in mesh with a worm gear 25 fast to one end of a shatt- 20 which is journaled at one end in the plate 1st and at its opposite end in the depending portion of the bracket 16. receives a feed roll 27 which clamped between cones 28 and 29 disposed at opposite ends o't'the shaft 26, the cone 28 preferably forming a part ot the shatt'and the cone 29 torming part ot a nut 30 which is thread ed upon an end ol the shaft 26. By looscning the nut 30 the teed. roll 27 may be rotated upon the shaft 26 to titllllitfif a new recoroii'ig and sales check strip being placed in position or adjusted, as required. When the nut 30 is tightened the feed roll 27 is clamped and caused to rotate with the shaft 26. The feed roll 27 is provided with a medial groove 31 to coact with a rotary cutter 32 for severing" the strip longitudinally. The feed roll 27 is also provided with spur teeth which mesh with the teeth of a spur gear 34 fast to the shalt 35 which carries the rotary cutter An end portion of the teed roll 27 is grooved to receive a drive belt 36 which transmits motion to the spool 37 upon which the retained portion of the strip is wound, Teeth 38 are provided at op ilos'ite ends of the feed roll 27 and malice positive engagement with the recording and sales check strip which, as shown in Figure 10, is provided along opposite edges with openings 39 which are engaged by the teeth 38. l

The shaft 35 is journaled at one end in the plate 14 and at its opposite end' in the depending portion of the bracket 16. The rotary cutter 32 is fast to the shaft and is adapted to co'ac'twith the feed roll to sever the strip 40 longitudinally, to term the sales check portion and the recor'dii'ig i portion, the latter being pret erably wound upon 7 spool 37, whereas the check portion divided to admit of each customer receiving a check indicating the purchase.

The shaft 26 The spur gear 34 transmits motion to the shaft from the shaft- 26. Grooved rollers t fast to the shaft 35 coact with the teeth 38 ot the teed roll 27 to prevent'disengagement of the strip 40 from the toothed portion. ot the feed roll and in consequence, the strip 40 can not be moved independently of the teed roll, and the latter cannot be moved without effecting a corresponding movement of the strip d0.

it spindle 43 is secured at one end to the plate 1 1, as shown most clearly in Figure 7 and receives the roll resulting from reeling the strip 40. The spool mounted upon the spindle 43 comprises a body 41 and heads 115, one end of the body l t'b'ein-g reduced and threaded to receive anut 46 and the opposite end out the body having a head 47. The core or center 48 upon which the strip 40 is wound is slipped uponthe body ddofthe spool and is clamped between the heads 4'5, it being understood that the nut 4. 6 and the adjacent head is reinovedto admit of placing the roll upon the spool, after which" the nut 46 and heads 15 are replaced. The roll adapted to turn-with the spool upon the spindle 43, the strip 40- being drawn from the roll by the member 27.

The spool 37 isloosely mounted upona; sphidle ill) which is secured at one end to the plate let in a manner sirnilar' to the spindle 4:23. This spool includes centero'r core 87 upon which the retained portionof the strip 40 is wound and which constitut es the record of the station. The part 37 is formed with a slot 50 through-'wlrich' an end portion of the strip'is passed, whereby to provide connection between the strip and spool, so that when the latter is'rotat'e'd the strip will be wound thereon. The numeral 51 designates the body of the spool, and 52" are heads clamped thereto by means oranut threadedupon a reduced end pol" tion of the body 51. An endportion of the spool body 51 is grooved to receive the drive belt 36 by means of which motion is transmitted from'theshaft 26 to the rewirrdiflg.

soool. The head of the spool body 51 is provided with lateral projections 54* to makepositive enga'geinelit withthe center or core 37 to insure rotation of the latter andthe winding of the recording or retained portion of the strip 40. An idle roll 55' is "osrtioned to one side of the spools 48and 37t0 give proper direction to the strip 40 topre vent lnterterrinp thereof with the parts'of the strip wound upon either or" the said spools. The guide roller 55 is mounted upon a spindle 56 which is secured at one end tothe plate 14 in a manner similar to the, spindles 43 were.

The numeral 57 designate-s dispensing pump, such as generall 1' )rovidedat serviee stations for supplying mot-or fuel and l'ubri eating il in measured quantity. The

tube. In accordance with the present invention, the projecting end of the shaft 17 is adapted to be coupled to the operating shaft 59 of the pump in any determinate way, so that the twoshafts 59 and 17 turn in unison. The pumpis of the type provided with the usual rack 60 and pinion 61 whereby the pump is operated upon rotation of the operating shaft 59 in the accustomed manner.

Rotation of the operating shaft 59 causes a corresponding movement of the shaft 17 and feed roll 27, whereby a portion of the strip 40 is drawn from the roll and projected through the delivery slot 12. hen a portion of the strip 40 is to be retained the latter portion is wound upon the spool 37 whereas the portion to be delivered is proj ected through the slot 12, the projecting portion being detached and given to the customer as a receipt or ticket to show the amount of motor fuel, or lubricating'oil deliver-ed.

Resilient guides62 project inwardly from i the front of thecasing in line with the delivand 64. A pressure member 65 of cam formation is mounted above the resilient guide 64 and is adapted to be operated to move the guide 64 to clamp the projecting portion between the guides 63 and 64, so that the projecting portion of the strip corresponding to the sales strip ticket, or receipt, may be conveniently severed or torn from the main portion of the strip. A crank handle 66 con nected with the pressure member 65 provides convenientmeans for operating the latter when it is required to clamp the strip between the guides 63 and 64.

When the door 11 is released and moved aside to admit of access to the interior of the casing a strip roll may be placed in position and the strip adjusted between the feed roll 27 and the retaining roll represented by the shaft and grooved rollers 42v An end portion of the strip may be passed over the guide roll and engaged with the rewinding roll 37 and the end portion of the strip corresponding to the sales check may be passed between the guides 62 through the delivery slot 12- and between the guides 63 and 64. After the strip has thus been adjusted, the door 11 is closed and locked,- thereby preventing any tampering with the mechanism. The strip 40 has longitudinal portions similarly designated to indieate units of measure, such as gallons, or quarts, depending upon the particular application of the mechanism. When the numeral 58 designates the usual delivery pump is operated the recording and sales check mechanism is correspondingly actuated, and a portion of the strip 40 1s delivered through the slot 12 and a portion wound upon the roll 37 corresponding to the amount of motor fuel, oil, or the like, de-

livered. The drive belt 36, transmitting motion from the feed roll shaft 26 to the rewinding spool 37 preferably consists of a wire coil, whereby the same is'at all times under tension and provision had for slip page as the relativediameter of the rolls or spool varies. hen the door 11 is moved to open position and the shaft 17 is uncoupled from the pump operating shaft 59 the entire mechanism may be removed from the casing 10 by detaching the plate or frame 14c from the blocks 13 and withdrawing the said plate or frame with the parts attached thereto through the open side of the casing. In this manner the mechanism may be readily inspected, or cleaned, or repaired, and easily and quickly placed in position.
